Liquiñe-Ofqui Fault

The Liquiñe-Ofqui Fault is major geological faultcite web|url=http://www.scielo.cl|accessdate=1999-07-01|publisher=CRED|title="Revista geológica de Chile"] that runs a length of roughly 1000 km in a north-south direction and exhibits current seismicity cite journal| last = Lange| first = D.| coauthors = Cembrano, J.; Rietbrock, A.; Haberland, C.; Dahm, T. and Bataille, K| title = First seismic record for intra-arc strike-slip tectonics along the Liquiñe-Ofqui fault zone at the obliquely convergent plate margin of the southern Andes,| publisher = Tectonophysics| month= April| year = 2008| volume = 455| issue = 1-4| doi = 10.1016/j.tecto.2008.04.014] . It is located in the Chilean northern patagonean Andes.

As the name implies it runs from the Liquiñe hot springs in the north to the Ofqui Isthmus in the south, where the Antarctic Plate meets the Nazca Plate and the South American Plate in Chile Triple Junction. A large parth of the fault runs along the Moraleda Channel. It may be classified as a dextral intra-arc transform fault.

The 1960 eruption of Cordón Caulle soon after the Great Chilean Earthquake was triggered by by movements in the fault.
